Thought I would do my part to help the communty

[Mr Bogus]

I think you already know that dyno sheets do not always relate to track times... is there plan to get this on the track to test the same setups? I am wondering if you can actually "out map" the ECU and 02 sensor in the real world out on the track..

I think there is a lot riding on your mapping at this point for the Gen2 bikes as it "so far" appears that the stock electronics can cope with a new pipe...

This should be good!

I agree, choose your weapon properly. Having real data to evaluate also helps no BS numbers here. Power through the rev range is exactly that. I am seeing the larger tubing exhaust systems are the way to go for sure. This bike won't like any little skinny down pipes.

If we can get the ECU to map to 12.8 13.0 13.1 AFR I think bolting on a pipe is all you will need track or street. Just a thought for now...lots more to do. I would like to look at the Ti-Force 4-2-2 and 4-2-1 and the Tsukigi pipes as well. Muzzy also has larger header pipe tubing for the 2008 Busa as well.

I will be at the track every weekend I possibly can

Air Filter testing:

Tested:

Stock
DNA
Pipercross Race
No-Air Filter

Testing all three filters showed no gain in horsepower or torque. However the OEM showed a 1HP loss. So OEM is just as good as the aftermarket filters except you can't clean and re-use it.

Just some more info for you guys!

 

[GPW]

The one thing that is pretty evident..they did there homework with this bike for sure. From the new air box on down.

Just as a side note what was the air temp on both dyno sessions, did both bikes have 42 psi in tires and were the chains properly lubed and adjusted what grade of fuel and brand did each bike have in it while they were both being tested, all are factors for comparison. And are those SAE or STD numbers I can't tell the way the graphs are posted its really fuzzy when you click to enlarge them I can't even make out the numbers in the graphs. Also how about a graph that shows time vs rpm on both exhaust I think that will tell alot about the differnt pipes. Thanks just my 2 cents.

They are SAE, I have a climate controlled dyno room stays at 69-72 degrees, always and has a 17 to 1 air exchange per minute. One of the best tuning facilities in the country we mocked what Dyno-Jet uses and added some other goodies. They are high res files on my screen. You have to double click them to view. Pretty simple, no tricks testing you can throw an 08 on your dyno and duplicate the same testing. Please post your results of your testing when you can, thanks.

I don't personally own a dyno but I have had more than one of my bikes on one just giving other people things to look out for when dyno testing trying to keep apples to apple in perspective. I also own an 08 Busa and will let others know of the results when I get it tuned locally by one of the best tuners in the country. By the way what gear were the pulls made in and what was the mileage and oil used in both bikes also as this too makes a difference in numbers. Thanks for the info.

4th. gear is the gear. Well I personally invite your best tuner in the country to come here and visit our state of the art facility. Should be featured in a three page article in next months Two Wheel tuner Magazine. We are working on a tuners challenge, everyone on the same equipment (DJ250i)starting with a zero map for speed and AFR flatline in every throttle position. I'll send you the info on the competition as soon as we get the sponsors lined up.

Tuning is really simple stuff when you have the right equipment. Some guys are still using the outdated non-calibrated junk. Tell Johnny Cheese I said hello.

It will be tough for some people if the Hayabusa needs no tuning for a basic pipe set-up. It is what it is. Integrity before dishonor something some in the industry are clearly lacking.

 

[Warchild]

Somehow... I have this sneaky little suspicion that *some* tuners will have *some* different numbers based upon *some* unmentioned, unspoken variable that, amazingly enough, fails to get mentioned anywhere.

But, I could be wrong.

I think it will weed out of the research and copy guys...

When cars did this, it simply changed the focus of the "modifications"

Rather than dump $600+ on PC and dyno time, they can purchase cams, or put some head work on the motor.. It will require a shop with real talent to stay on top of this...

I am somewhat encouraged that you are doing this.. I can hardly wait to see what your suggestions for modifications are going to be in the end...

I think you are adding to the credibility of those recommendations with this type of "freebie" for us all...

I think it's great that a manufacture actually got it right

 

[Mr Bogus]

was pretty much Govt mandated

(emission standards can be a lot of fun)

 

[GPW]

I think it's great that a manufacture actually got it right

That is the part that impresses me the most about all of this. People were looking at just CC's for a while and the bulk of the improvements were right in front of your eyes. This bike went from 163-165 HP piped and tuned to 180-184 hp..with no tuning needed just a pipe and pump gas.

Greg, you're the man, thank you for your honesty. It's people like you that restore faith in businesses like yours. Again, thanks for sharing.

GPW,
It is indeed refreshing to see a shop post real data of what is actually happening and not scew results for the prusuit of the almighty $$$ . congrats to you and your shop ! I am sure there are manfactures ,tuners and shops that will refute your findings for nothing more than making more $$$ I applaude you sir ... keep up the good work

 

[Elganja]

We also saw that in modes B & C the perfect AFR curve goes hay wire confirming that the PCIII only addresses the mapping in the mode you map the bike in, in my case mode "A".

You know greg thinking about this more and more it makes complete sense along with your other findings.

IIRC, you said that the B and C mode affect the Secondary Throttle plates. The dynojet power commander "intercepts" the signal on the primary throttle plate injectors only; it never touches the secondary throttle plate fuel injectors.

So, if you tune for Mode A (say 3/4 open secondary) then it makes sense that in mode B (say 1/2 open secondary) that the tune is all jacked up. You excepted the secondary plates to be open 3/4 but they were only open 1/2 way...

Anyways... it all makes sense... i never used B or C anyways. Maybe the switch can be converted to something else (air shifter maybe? who knows!)...

Thank you very much. I too spent 20 years on the other side of the counter. I was told every BS lie in the book while trying to get my bikes to go faster as a consumer. When we opened the shop(s). I was crystal clear on we would take the high road in sales, service, quality products and integrity. Thank you for seeing our vision. We plan to open up two more HPC's in the next 18 months one in the southern states and one north of Maryland. Not coming from a racing background was a good thing it made seeing what was screwed up that much easier.
